  1. 1. Colloidal Organic Pollutants in Road Runoff: Sources, Emissions and Effective Treatment Technologies

    Författare :Anna Markiewicz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic pollutants; nanoparticles; stormwater; sorption filters; road dust; emulsions; washwater; vehicle wash; road runoff; microparticles; sweepsand; colloids; street sweeping;

    Sammanfattning : Thousands of organic substances circulate in our society and are diffusely emitted through traffic, combustion and leaching from constructions and building materials into the urban environment. The research in this PhD thesis focuses on road runoff as the highest concentrations of pollutants are frequently found in runoff from areas with high traffic intensity. LÄS MER

  3. 2. On-site wastewater treatment : Polonite and other filter materials for removal of metals, nitrogen and phosphorus

    Författare :Agnieszka Renman; Per-Erik Jansson; Lars D. Hylander; Gunno Renman; Björn Klöve; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkaline materials; heavy metals; mechanisms; nutrient removal; sorption; speciation modelling; Environmental engineering; Miljöteknik;

    Sammanfattning : Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. LÄS MER

  4. 3. Modern landfill leachates – quality and treatment

    Författare :Hanna Modin; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy metals; European Landfill Directive; Biodegradation; Landfill leachate; Leaching tests; Multivariate data analysis; Organic matter; Sorption filters;

    Sammanfattning : Waste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. LÄS MER

  5. 4. Phosphorus transport and reduction in compact-bed filters : simulations and experiments

    Författare :Amir Jourak; Andy George; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Excessive release of phosphorus from the effluent of on-site sanitation facilities to the environment is one source of aquatic pollution. The primary effect of excess phosphorus in the aquatic environment is eutrophication. LÄS MER

  7. 5. Reactive filter materials for ammonium and phosphorus sorption in small scale wastewater treatment

    Författare :Annelie Hedström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Existing small scale wastewater treatment systems in Nordic countries have generally low treatment efficiency regarding phosphorus and nitrogen. Even though only 15% of the Swedish population is connected to on-site wastewater treatment systems, the total discharge of phosphorus from these systems exceeds the total discharge from all municipal treatment plants in Sweden.
